Knit shipped a brand-new Timesheet API in a week and handed us a ready-to-use NetSuite sandbox. That velocity is priceless when you're running payroll in 40+ countries.

FAQ

Common questions about Karbon + Double HQ

Is there a pre-built Karbon + Double HQ automation?

Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches Karbon and Double HQ's public API docs (or your own uploaded docs) and builds a working automation.

Does this require a pre-built Karbon or Double HQ connector?

No. The Agent works whether or not Karbon or Double HQ already has a pre-built connector in Knit's catalog — it researches the real API surface either way.

How long does it take to build?

Minutes to build a first working version, not weeks — you test it against real data before it goes anywhere near production.

Why integrate two separate project management tools like Karbon and Double HQ?

It enables seamless cross-departmental or agency-client collaboration by mirroring tasks, updates, and comments across both platforms in real time.

Will comments added in one app sync to the other?

Yes, when a team member adds a comment in Karbon, that note can automatically be added to the corresponding task in Double HQ.
